[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.
[0023] Specific implementation examples are given below.
[0024] Please see Figures 1-4This utility model provides a paper packaging box printing machine with an adjustable function, including a printing machine body 1; a vertical plate 11 is fixedly connected to the side wall of the printing machine body 1; a bidirectional screw 12 is rotatably connected to the side wall of the vertical plate 11; a sliding rod 13 is fixedly connected to the side wall of the vertical plate 11; a support block 14 is fixedly connected to the side wall of the sliding rod 13; the bidirectional screw 12 passes through the support block 14 and is rotatably connected to it; a pair of connecting blocks 15 are threadedly connected to the side wall of the bidirectional screw 12; the connecting blocks 15 are symmetrically arranged on both sides of the bidirectional screw 12 and have the same structure; a pair of collars 16 are symmetrically sleeved on the outer side of the sliding rod 13; the collars 16 and the connecting blocks 15 are fixedly connected; a baffle 17 is fixedly connected to the side wall of the connecting block 15; a limit plate 18 is hinged to the side wall of the baffle 17; in use, first rotate the bidirectional screw 12, and under the threaded engagement of the bidirectional screw 12 and the connecting blocks 15, the connecting blocks 15 can be moved closer or further apart, and the sleeves can be rotatably connected to the connecting blocks 15. Ring 16 slides on the side wall of slide bar 13, limiting the movement of connecting block 15 and preventing it from rotating, thus adjusting the distance between baffles 17. When the limiting plate 18 moves to a relatively edge, it can be tilted by squeezing it. When the limiting plate 18 moves away from the edge of the printing machine body 1, it can be reset by the action of the internal torsion spring at the hinge of the limiting plate 18. Then, when the printing machine body 1 feeds the paperboard, the inclined surface of the limiting plate 18 can make the paperboard slide towards the middle of the two limiting plates 18, limiting the movement of the paperboard. At the same time, the baffles 17 can keep the paperboard moving continuously for a period of time. During this process, the printing machine body 1 can limit the movement of the paperboard during the feeding of the paperboard, reducing the occurrence of tilting during the movement of the paperboard. The connecting block 15 can limit the movement of paperboards of different sizes, improving the adaptability of the baffles 17 and increasing the limiting range of the baffles 17.
[0025] Furthermore, such as Figures 1-4As shown, a connecting pipe 2 is fixedly connected to the side wall of the support block 14; a guide pipe 21 is fixedly connected to the side wall of the connecting pipe 2; a plurality of first air outlet holes 22 are evenly opened on the side wall of the connecting pipe 2; a pair of extension pipes 23 are slidably connected to the inner side wall of the connecting pipe 2; the extension pipes 23 are symmetrically arranged on both sides of the connecting pipe 2 and have the same structure; a plurality of second air outlet holes 24 are evenly opened on the side wall of the extension pipes 23; in use, by connecting the guide pipe 21 to an external air pump, the air pump supplies air to the connecting pipe 2, and the airflow enters through the connecting pipe 2. Inside the extension tubes 23 on both sides, the airflow is finally sprayed out to the outside through the first air outlet 22 and the second air outlet 24, which can blow air onto the surface of the cardboard. During the movement of the connecting block 15, the extension tubes 23 can also be moved, allowing them to slide inside the connecting tube 2, thereby adjusting the blowing range. In this process, it can clean the dust and impurities attached to the surface of the cardboard, reduce the residue of dust and impurities on the surface of the cardboard during printing, and thus improve the printing effect of the cardboard. At the same time, it can also remove dust from cardboard of different sizes.
[0026] Furthermore, such as Figures 1-4 As shown, a fixed plate 3 is hinged to the side wall of the baffle 17; the fixed plates 3 are rotatably connected to the same rotating shaft 31; multiple cleaning brushes 32 are evenly fixed to the side wall of the fixed plate 3; a connecting rod 33 is fixed to the side wall of the cleaning brush 32; the connecting rod 33 passes through the wall of the cleaning brush 32 and is fixed to it; in use, when the baffles 17 move away from each other, the rotating shaft 31 can be rotated, causing the fixed plates 3 on both sides to be gradually straightened; when the baffles 17 move closer to each other, the fixed plates 3 can be tilted by squeezing. Then, when the printing press body 1 conveys the paperboard, the cleaning brushes can be used to tilt the paperboard. The brush 32 can clean the surface of the cardboard, removing the attached dust and impurities. At the same time, the connecting rod 33 can fix multiple cleaning brushes 32 together, so that the cleaning brushes 32 are concentrated together during cleaning. In this process, it can further clean the dust and impurities attached to the surface of the cardboard, improve the printing effect of the cardboard. The connecting rod 33 can also increase the concentration of the cleaning brushes 32 during cleaning, thereby increasing the cleaning effect. Furthermore, the air blown by the first air outlet 22 and the second air outlet 24 can clean the dust and impurities attached to the surface of the cleaning brushes 32.
[0027] Furthermore, such as Figures 1-4As shown, the connecting block 15 has a spring rod 4 on its side wall; a wax block 41 is fixed to the end of the spring rod 4; during use, as the connecting block 15 moves, the surface of the bidirectional screw 12 can be wiped by the contact between the wax block 41 and the bidirectional screw 12. At the same time, the wax block 41 will continuously decrease after wiping for a long time. At this time, the elasticity of the spring rod 4 can push the wax block 41 to always be in contact with the surface of the bidirectional screw 12. In this process, it can play a lubricating role on the surface of the bidirectional screw 12, improve the smoothness of rotation between the bidirectional screw 12 and the connecting block 15, and reduce the occurrence of corrosion of the bidirectional screw 12, thereby improving the service life of the bidirectional screw 12.
[0028] Furthermore, such as Figures 1-4 As shown, the connecting block 15 has a slot 5 on its side wall; a fixing block 51 is slidably connected to the side wall of the slot 5; a rubber pad 52 is fixedly connected to the side wall of the fixing block 51; the fixing block 51 is fixedly connected to the spring rod 4; in use, by inserting the fixing block 51 into the slot 5, the rubber pad 52 is fully in contact with the slot 5 and a certain friction is generated, so that the wax block 41 can be installed and fixed. In this process, the wax block 41 can be conveniently disassembled and installed, and the wax block 41 can be easily disassembled and replaced, thereby increasing the practicality of the wax block 41 in use.
[0029] Furthermore, such as Figures 1-4 As shown, multiple rotating wheels 6 are evenly rotatably connected to the side wall of the limiting plate 18. In use, when the limiting plate 18 blocks and limits the cardboard, the rotating wheels 6 can be driven to rotate as the cardboard moves, making the cardboard move more smoothly on the side wall of the limiting plate 18. In this process, the rotating wheels 6 can increase the smoothness of the cardboard moving on the side wall of the limiting plate 18, reduce the friction between the cardboard and the limiting plate 18, and thus increase the limiting speed of the cardboard.
[0030] Working principle: In use, first rotate the bidirectional screw 12. With the threaded engagement between the bidirectional screw 12 and the connecting block 15, the connecting blocks 15 can move closer or further apart. Simultaneously, the collar 16 slides on the side wall of the slide rod 13, limiting the movement of the connecting blocks 15 and preventing rotation. This allows adjustment of the distance between the baffles 17. When the limiting plate 18 moves to a relatively edge, pressing the limiting plate 18 can cause it to tilt. When the limiting plate 18 moves away from the edge of the printing machine body 1, the internal torsion spring at the hinge of the limiting plate 18 allows it to tilt. After resetting, when the printing press body 1 feeds the cardboard, the inclined surface of the limiting plate 18 allows the cardboard to slide towards the middle of the two limiting plates 18, limiting the movement of the cardboard. At the same time, the baffle 17 can keep the cardboard moving continuously for a period of time. In use, by connecting the guide pipe 21 to an external air pump, the air pump supplies air to the connecting pipe 2. The airflow enters the two extension pipes 23 through the connecting pipe 2, and finally the airflow is sprayed out to the outside through the first air outlet 22 and the second air outlet 24, which can blow air onto the surface of the cardboard. During the movement of the connecting block 15, the extension pipes can also be driven. The tube 23 moves, allowing it to slide within the connecting tube 2, thus adjusting the blowing range. During use, when the baffles 17 move away from each other, the rotating shaft 31 rotates, gradually straightening the two fixed plates 3. When the baffles 17 move closer together, the fixed plates 3 tilt due to pressure. Then, when the printing press body 1 conveys the cardboard, the cleaning brush 32 cleans the surface of the cardboard, removing attached dust and impurities. Simultaneously, the connecting rod 33 securely connects multiple cleaning brushes 32, concentrating them together during cleaning. During use, the connecting block 15 moves... During the process, the surface of the double-ended screw 12 can be wiped by the contact between the wax block 41 and the double-ended screw 12. At the same time, the wax block 41 will continuously decrease after wiping for a long time. At this time, the elasticity of the spring rod 4 can push the wax block 41 to always keep in contact with the surface of the double-ended screw 12. When in use, the wax block 41 can be installed and fixed by inserting the fixing block 51 into the slot 5, so that the rubber pad 52 is in full contact with the slot 5 and generates a certain friction. When in use, when the limiting plate 18 blocks and limits the cardboard, the movement of the cardboard can drive the rotating wheel 6 to rotate, so that the cardboard moves more smoothly on the side wall of the limiting plate 18.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
